You can skip. I get that front end stuff can be intimidating. My recommendation is to learn the basics and when it comes to libraries fight the intimidation and take a few minutes to try out new technology when you encounter it. If you find it too hard in those few minutes of actually trying it, don't use it. You can still use script tags if you want. Your site will run just fine. Do what feels comfortable. These tools are supposed to make your life easier, not harder.
Having said that grunt is very bad because it is intimidating even for seasoned front-end programmers, it probably scared a lot of new developers away from even looking at front-end build systems. That's probably a good reason why it should fall off the radar. Thankfully gulp is much easier and I bet if you try it you will find it useful. If you don't, that's OK.
